IMPROVEMENT IN TUBULAR APPARATUS FOR DEEP WELLS.

Specification forming part of Letters Patent No. 50,9 B9., datedNovember 14, 1865.

To all whom it 'may concern:

Beit known that we, M. J. DIOKERsON, ot' Titusville, county of Venango,and State of Pennsylvania, and JACOB ST UBER, of the city of Utica,county of Oneida, and State of New York, have invented a new andImproved Method of Packing Artesian Wells, so that oil and other liquidsmay be more advantageously raised therefrom; and we do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Fgure I is a longitudinal section representingthevdriving-tubing and the walls of the well, eduotion-tubin g,packing-tubing, steam or air pipe, arranged and combined according tothe principles of ourinvention. Fig. Il is a transverse section.

The nature of vour invention consists, tirst, 1n the application and useof a distinct packing-tube, around or to which the seed-bag is attached,and made of larger diameter than the eduction-tube, and through whichthe eduction-tube passes, so that the eduction-tube may beinserteil,removed, or raised or lowered, adjusted, and placed in its properposition without disturbing the seed-bag or unpacking the Well; second,in the combination and arrangement therewith of a steam or air pipeentering between the eduetion-'tube and the packing-tube, for thepurpose ot forcing air or steam into the well for any purpose for whichair or steam may be used therein; third, in

' the connection and combination therewith of a stop-cock (to which apipe may be connected) for directing the gas which collects in the wellto the boiler for fuel, or for any other purpose for which such gas maybe used.

Letters of like name and kind refer to like parts in each of the gures.

It is known to those who have much experience in sinking Artesian wells,and in raising oil and other liquids therefrom,that for the successfuloperation thereof the surface-water7 (so called) must be shut off fromthe oil or other liquids below which it is the object of the well tosecure.

A device called a seed-bag 7 has heretofore been used for this purpose,and has been apphed 1n a manner to form an annular packing around theeduction-tube and between it and the walls ofthe well; but this isattended with many practical difficulties, which it is the object of ourimprovement to overcome. Forinstance, it often becomes necessary toremove the ed uction-tube to repair the same, or to repair the lowervalve, or to change the position of its lower end, in order to get it inits right place to catch the oil. Every such removal or change ofposition of the eduction-tube causes the destruction ot' the seed-bag,and,

hence unpacks the well, and allows the surface-water (with itssedimentary deposits) to fill the well, and mingle with the oil or otherliquids, which it is the purpose ot' the well to obtain, thereby greatlyincreasing the expenses of working the well and rendering its productsless valuable. When the seed-bag becomes iirmly packed around theeduction-pipe it requires great power applied to the eduction-pipe torelease it from the pressure of the seed-bag. This often breaks orsplits the eduction-pipe, (the seed-bag being necessarily destroyed inthe operation,) and hence much loss and expense, besides waste of time,is incurred; also, in the old way of packing these Wells, it' steam orair is used therein, the steam or air pipe must be carried through theseed-bag, and the hot steam will heat the pipe sufticientlyto burn orshrink the seed-ba g, causing it'to leak, so that the surface-water willtrickle through and injure and retard the working of the well.

Our improvement affords a remedy for all these and other difficultiesnot herein inentioned.

A represents the drivin g-tube, which is usually made tive or six inchesin diameter, more or less. This is driven into the soft earth until itreaches the rock in a common manner.

B represents the walls of the well below the drivin g-tube.

O represents a distinct packing-tube, which is made of larger diameterthan the eductiontube, so that the eduction-tube has ample room to passthrough it, and of smaller diameter than the driving-tube and bore ofthe well, so that the seed-bag may be iitted around it and form apacking between it and the walls ot' the well. This packing-tube isgiven any re quired length sufcient to reach below the driving-tube andsupport the seed-bag at such place in the Well as may be scclected forthe most advantageous packing thereof.

The seed-bag is shown at l), and is', so far as the bag itself isconcerned, of ordinary construction. lt is combined with and made fastto the packing-tube c, as shown, so as to form a packing between thetube and the walls of' the well. When this packing-tube and seedbagconnected therewith are placed in lthe proper position in the well so asto shut off the surface-Water, they may remain there permanently withoutbeing disturbed by the placing or removing` or changing the position otthe eduction-tube. They may be placed in position before theeducton-tnbe is pnt in. They form a surface-Water chamber entirelyseparate from and independent of the eduction-tubing, pump, and steamand air pipe. A collar is formed around the top of the packingtube, asshown at c', which maybe tightly fitted by a screw or otherwise to thedrivingtube, as shown.

The eduction-tube is represented at E. This is of ordinary constructionand use, and is inserted into the Well, passing through thepacking-tube. Appropriate valve, valve piston, andpiston or pump rodareinserted therein to form a pump, as in a common manner, or theeduction-tube may be used without these when steam or compressed air isused to force the liquid out.

F is a valve; Gr, valve-piston; H, pistonrod. l is an ordinarystul'ling-box, through which the piston-rod Works.

J represents a steam or air pipe, which is conducted into the wellthrough the packingtube, and through which steam or air may be forced ina common manner Whenever itis desirable to use steam or air in the wellfor any purpose.

K represents a stop-cock, which is fitted into the head-cover of thewell and opens into the well, so as to let ot't'- any gas Which may co1-lect therein. A pipe is connected to this stopcock, which may be led oifto the boiler er furnace, and the gas used for fuel or for other usefulpurpose-s. The steam -pipe does not pass through the seed-bag, asheretofore, when the seed-bag was packed around the eductionpipe, but isentirely free therefrom.

L is an opening from the surface-Water chamber, into which a pipe maybeinserted for the purpose ot' conducting ott' any surplus water that maycollect therein.

What we claim, and desire to secure by Letters Patent, is

l. The formation ot' a surface-Water chamber separate from theeduction-tnbe by means of the application and use of a packing-tube, G,driving-tube A, and seed-bag (or other packing) D, for the purposes andsubstantially as described.

2. The combination and arrangement of the steam-pipe J', stop-cock K,and packing-tube C, substantially as described.
